Next, the tray 300 moves forward relative to the connector body 200 . Therefore, as shown in FIGS. 3 and 5 , the connector body 200 and the tray 300 are in a receiving state in which the tray 300 is received in the tray receiving portion 205 of the connector body 200 .

Meanwhile, referring to FIG. 5 , the mechanism accommodating portion 360 of the tray 300 simultaneously accommodates the pushing portion 223 and the ejection lever 222 of the first member 210 of the connector body 200 . Specifically, in the receiving state, the eject lever 222 of the first member 210 of the connector body 200 is partially accommodated in the mechanism accommodating portion 360 of the tray 300 . In addition, in the received state, the push-out portion 362 of the mechanism accommodating portion 360 of the tray 300 is in contact with the push portion 223 of the eject lever 222 of the first member 210 of the connector body 200 in the front-rear direction.

At the same time, referring to FIG. 6, the detection switch 240 of the first member 210 of the connector body 200 is at least partially accommodated in the switch accommodating portion 370 of the tray 300, and the switch operation portion 372 of the switch accommodating portion 370 of the tray 300 is pushed to connect The operated part 242 of the detection switch 240 of the first member 210 of the device main body 200 is operated to operate the detection switch 240 . Accordingly, the detection switch 240 of the first member 210 of the connector body 200 can detect a receiving state in which the tray 300 is received in the connector body 200 .

In addition, referring to FIG. 3 , each held portion 390 of each groove 385 of the tray 300 is at this time aligned with each holding spring of each side wall 213 of the first housing 211 of the first member 210 of the connector main body 200 at this time along the front and rear directions. 230 contacts. More specifically, each held portion 390 of each groove 385 of the tray 300 at this time receives at least forward force from the holding spring 230 of the corresponding side wall 213 of the first housing 211 of the first member 210 of the connector body 200 . force. Therefore, if the eject lever 222 is not operated in the receiving state where the tray 300 is received in the connector body 200 , the tray 300 can be prevented from being ejected backward from the tray receiving portion 205 of the connector body 200 . In other words, in this case, the receiving state in which the tray 300 is received in the tray receiving portion 205 of the connector main body 200 is maintained.

The movement and state of the components of the connector body 200 and the tray 300 in the case where the tray 300 is ejected from the connector body 200 will be described in detail below.

First, referring to FIGS. 3 and 16, in the received state where the tray 300 is received in the connector main body 200, when the eject bar 226 is moved forward in the front-rear direction by being pushed by a thin rod (not shown) or the like, The shaft hole 224 of the eject lever 222 is pressed against the shaft portion 225 , and the pressed portion 229 of the eject lever 222 is pressed against the front wall 212 of the first housing 211 . In other words, when the eject bar 226 starts to move forward in the receiving state where the tray 300 is received in the connector body 200 , the eject bar 222 presses against the front wall 212 . Therefore, the forward movement of the eject bar 226 will exert a forward force on the eject bar 222 , and the forward force is distributed to the shaft portion 225 of the eject mechanism 220 and the front wall 212 of the first housing 211 . Specifically, the front wall 212 serves as the reinforcing shaft portion 225 .

Forward movement of the eject lever 226 causes the engaging portion 227 of the eject lever 226 to apply a forward force to the engaged portion 228 of the eject lever 222 . Accordingly, a rotational moment is generated around the shaft portion 225 of the eject lever 222 so that a rearward force is applied to the push portion 223 of the eject lever 222 .

At the same time, the pushing portion 362 of the mechanism accommodating portion 360 of the tray 300 is pushed backward by the pushing portion 223 of the ejecting lever 222 of the first member 210 of the connector body 200 .

In other words, when the eject bar 226 moves forward in the front-rear direction in the receiving state where the tray 300 is received in the connector body 200, the eject bar 222 moves around the shaft portion 225 as a fulcrum so that the pushing portion 223 is pushed out. Section 362.

When the push-out portion 362 of the mechanism accommodating portion 360 of the tray 300 is pushed backward by the pushing portion 223 of the ejection lever 222 of the first member 210 of the connector body 200, the held portion 390 of each groove 385 of the tray 300 will move forward and backward. A force directed backward and outward in the width direction is applied to the retaining spring 230 of the corresponding side wall 213 of the first housing 211 of the first member 210 of the connector body 200 .

After that, when the ejection bar 226 moves further forward, the further forward movement increases the force applied to the holding spring 230 through the corresponding held portion 390, the force is rearward in the front-rear direction and lateral in the width direction. outside, so that the retaining spring 230 elastically deforms outward in the width direction. Then, contact in the front-rear direction is broken between the held portion 390 of each groove 385 of the tray 300 and the holding spring 230 of the corresponding side wall 213 of the first housing 211 of the first member 210 of the connector body 200 .

When the ejection bar 226 is still moving further in this state, the push portion 223 of the ejection bar 222 of the first member 210 of the connector body 200 further pushes the ejection portion 362 of the mechanism accommodating portion 360 of the tray 300 backward, so that the tray 300 is ejected rearwardly from the tray receiver 205 of the connector body 200 through the opening 206 . In other words, the received state in which the tray 300 is received in the connector main body 200 is released as shown in FIG. 9 .

Although the specific explanation of the present invention has been given above with reference to the respective embodiments, the present invention is not limited thereto, and various modifications and substitutions can be made.

Although the ejection mechanism 220 of this embodiment has a shaft portion 225 , an ejection lever 222 , a pushing portion 223 and an ejection bar 226 , the present invention is not limited thereto. Specifically, the ejection mechanism 220 may not have the ejection bar 226 . It is sufficient that the ejection mechanism 220 has at least a pushing portion 223 that pushes the tray 300 when the tray 300 is ejected. Additionally, the eject mechanism 220 may have a push mechanism instead of the eject lever 222 . As described above, in the receiving state where the tray 300 is received in the connector body 200 , the held portion 390 of each groove 385 of the tray 300 receives at least Corresponding to the forward force of the retaining spring 230 of the side wall 213 . Therefore, in order to push the tray 300 backward against the resistance of the retaining spring 230 without increasing the size of the card connector 100 , the eject lever 222 of this embodiment is a better solution than the pushing mechanism.

The above are the preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the present invention, any technical solution based on the present invention, etc. Obvious changes such as effective conversion and simple replacement all fall within the protection scope of the present invention.
